Tracking Roller

Tracking Roller is an item used by Marin Production, although the inventor is still unknown. This device had only appeared in RagingTrollers' small episodes of BlazeClan Chronicles (not exactly canon, but it's also not impossible to be on the actual timeline).

Function
Tracking Roller can be able to follow the target desired by the user, and run as fast (if not faster) than RagingTroller's running speed (especially sprinting).

Drawback
Since this device had only been used in small episodes, and not on the main ones, there had been no actual drawbacks. If anything, it's common for devices to need certain power source, but it's unknown where it came from.

Trivia

 * Despite Marin supposedly possessed the device, it's name rhymed with RagingTroller's name. Not because it's name was mentioned later, but the function fits the name too.
